Happy Valentine's Day! Today's video features an engineering student who designed a 3-D printer that makes chocolate confections. He envisions his printer as an entertainment device for weddings and other social gatherings.

Researchers have successfully 3-D printed unweldable aluminum alloys, incorporating zirconium-based nanopowders into the additive manufacturing process, which prevents hot cracking. They say they can now make any unweldable metal weldable using this process.

The U.S. Navy created a submersible hull prototype on a giant 3-D printing machine in less than one week—saving the Navy 90% in production costs. This is the first step in building a fleet of submersibles that can withstand harsh ocean conditions.

A 3-D printed structure created by a collaboration of engineers attracted the attention of Guinness World Records. Watch the video to see how the researchers printed the world's lightest structure made out of 3-D printed graphene aerogel and earned a spot in the 2018 edition.

Jennifer Lewis's Harvard-based research group is the first to develop and market a 3-D printer that can incorporate conductive inks and plastics into 3-D printed electronics through their spinoff company, Voxel8.
